The intense yearning for liberation or moksha is called mumukshatwam in Sanskrit.
What does this intense yearning look like?
There’s a story about the great Swami Vivekananda with his Guru Sri Ramakrishna Paramhamsa. Apparently the former had this very same question too. So his Guru asked him to take a dip in the Hooghly river in Calcutta (or Kolkata). And then pushed his head down in the water (like the villain would do to a hero in a Hollywood movie, and vice versa in a Bollywood movie!) not allowing Vivekananda to come up for air.
Needless to say, the only intense yearning at that point was for oxygen. Not any money or or material objects.
That was how much intense yearning was required for moksha as well.
